Player for custom datasource

Question

Hi
I need to create a custom datasource but i want to play it on a player as other normal datasource.
I tell you what im doing, I have developed a example to show you my problem:
first thing i do is creating a custom datasource:
import javax.media.*;
import javax.media.protocol.DataSource;
import javax.media.protocol.ContentDescriptor;
public class myCustomDataSource extends DataSource {
     myCustomDataSource(MediaLocator ml){}
     public void connect(){}
     public void disconnect(){}
     public void start(){}
     public void stop(){}
     public String getContentType() {
          return ContentDescriptor.CONTENT_UNKNOWN;
     public Object[] getControls() {
         return new Object[0];
     public Object getControl(String type) {
         return null;
     public Time getDuration(){
          return Time.TIME_UNKNOWN;
}then, I create a basic class that use a player for playing my custom datasource:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.media.*;
import javax.media.protocol.DataSource;
public class VideoPlayer extends JFrame {
     Player player = null;
     private JPanel contentPane;
     public static void main(String args[]){
          String mediaFile = "http://noodle.med.yale.edu/demos/dsr_arrow.mpg";
          MediaLocator locator = new MediaLocator(mediaFile);
          myCustomDataSource mcds = new myCustomDataSource(locator);
          (new VideoPlayer(mcds)).setVisible(true);
     public VideoPlayer(myCustomDataSource ds) {
          super("Example");
          setSize(400,400);
          contentPane = (JPanel) this.getContentPane();
          addWindowListener(new myWindowAdapter());
          try {
               player = Manager.createPlayer(ds);
               player.addControllerListener(new controllerUpdate());
          }catch(Exception e){
               System.err.println("Error loading the media. ("+e+")");
          if(player!=null) player.realize();      
     class controllerUpdate implements ControllerListener {      
          public synchronized void controllerUpdate(ControllerEvent e) {      
               if(e instanceof RealizeCompleteEvent) {
                    Component visualArea = player.getVisualComponent();      
                    Component controlPanel = player.getControlPanelComponent();      
                    if(visualArea!= null)      
                         contentPane.add(visualArea, BorderLayout.CENTER);      
                    if(controlPanel != null)      
                         contentPane.add(controlPanel, BorderLayout.SOUTH);      
                    validate();      
                    player.prefetch();
               if(e instanceof PrefetchCompleteEvent) {
                    player.start();
     class myWindowAdapter extends WindowAdapter {
          public void windowClosing(WindowEvent e){
               if(player!=null) player.close();
                    System.exit(0);
}when i run it i get the next error: Error loading the media. (javax.media.NoPlayerException: Cannot find a Player for: myCustomDataSource@be0e27)
I dont know how i must fill the myCustomDataSource class constructor and abstract methods to run it.
I test videoplayer class with a normal datasource and it works
sorry for my bad english
Thanks so much

ok, thanks for answering,
I see a sun webpage example maybe can help: http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/JpegImagesToMovie.html
In that example, a custom datasource is declared and then a processor is created with that custom datasource using Manager.createProcessor. For that, custom data source class is declared inside class where processor is used. Im trying to do it but it doesnt work, i get the same error.
thanks in advance
